Computer aided designing of microwave frequency discriminator

摘要

Microwave frequency discriminator (MFD) is a device, which is used to generate signal carrying information about frequency of input signal. Depending on type of subassemblies, which were used in examined MFD, its parameters will change. Developed simulator BP-PK-V2.0 is able to measure frequency of virtual or obtained from measurement by other microwave devices signals. Its most important feature is, that the program enables its user to test parameters of discriminator created from certain subassemblies without manufacturing physical device and, when the results are not satisfactory, remodeling its structure with one or more elements. Tests will end when expected performance is achieved and only then should simulated MFD be implemented in PCB. Two types of visualization, in which described simulator is equipped with, enable to determine properties of two methods of estimating measured value: continuous method (with high resolution) and discrete method, in which information precision is limited to subrange with finite width.
